Assessment Notes

Taxonomic notes

Why suggested for a Global Red List Assessment?

This ectomycorrhizal species is strictly associated with Nothofagus and is only known from a single collection in the Aysen region of Chile.

Geographic range

This species occurs in Nothofagus forest in the Aysen region of Chile.

Population and Trends

Geomorium furciae is only known from one locality in a Nothofagus dombeyi forest in the Aysen region of Chile (Melimoyu Natural Reserve). This is a conspicuous and easily recognizable species that is not easily overlooked, thus it is most probably very rare. However, there have been few mycological studies in this area compared to other regions of Patagonia, thus other populations may exist.

Population Trend:

Habitat and Ecology

This ectomycorrhizal species associates exclusively with Nothofagus species in Patagonia. So far it has only been found in an old growth Nothofagus dombeyi forest in the Aysén region of Chile (Melimoyu Natural Reserve).

Subantarctic Forest


This species is associated with an increasingly threatened Nothofagus forest. Deforestation and forest fires (intentional and accidental due to drought and climate change) are a growing threat.

Increase in fire frequency/intensityHabitat shifting & alteration

Conservation Actions

The only known locality of Geomorium furciae lies within a protected area (Melimoyu Natural Reserve).

Site/area protection

Research needed

Little is known about the biology of the species (fruiting patterns) as well as its ecology (habitat requirement, host specificity) and functions for his Nothofagus host. Further research is needed in the area to find out whether more populations exist.
